    摘要: An ignition apparatus for an internal-combustion engine includes a main ignition CDI circuit that has a main ignition boosting circuit boosting battery voltage and a main ignition capacitor storing electric charge boosted by the main ignition boosting circuit, and that releases the electric charge stored in the main ignition capacitor to a primary coil of an ignition coil to make an ignition plug generate spark discharge, and an energy input circuit that has an energy input boosting circuit boosting battery voltage and an energy input capacitor storing electric charge boosted by the energy input boosting circuit, and that releases the electric charge stored in the energy input capacitor to the primary coil, during a spark discharge started by operation of the main ignition CDI circuit, to make a secondary current flow in the same direction and to a secondary coil of the ignition coil, thereby making spark discharge continue which is started by the operation of the main ignition CDI circuit.

    摘要: An ignition circuit and a method of operating an igniter (preferably a traveling spark igniter) in an internal combustion engine, including a high pressure engine. A high voltage is applied to electrodes of the igniter, sufficient to cause breakdown to occur between the electrodes, resulting in a high current electrical discharge in the igniter, over a surface of an isolator between the electrodes, and formation of a plasma kernel in a fuel-air mixture adjacent said surface. Following breakdown, a sequence of one or more lower voltage and lower current pulses is applied to said electrodes, with a low “simmer” current being sustained through the plasma between pulses, preventing total plasma recombination and allowing the plasma kernel to move toward a free end of the electrodes with each pulse.

    摘要: A controller used to control a flyback switching mode power supply. The flyback switching mode power supply is constructed to charge a capacitor, and includes a rectifying device, a series arrangement of a switch and a primary winding of a transformer for receiving an input voltage, and a secondary winding of the transformer for charging the capacitor via the rectifying device to an output voltage. The controller is configured to sense the output voltage and to turn on the switch when the change of the output voltage over time becomes smaller than a predetermined threshold. By using the controller to sense and use the output voltage across the capacitor to turn on the switch, a controlled flyback switching mode power supply that makes use of voltage control is realized.

    摘要: The present invention has an object to provide a semiconductor device that has protective functions and is capable of achieving miniaturization and cost reduction. A semiconductor device according to the present invention includes a switching element, a drive circuit, and a control circuit. When a high-level drive control signal is output from the drive circuit, the control circuit stops driving of the switching element and charges an electric charge storing capacitor. When a low-level drive control signal is output from the drive circuit, the control circuit drives the switching element using electric charges stored in the electric charge storing capacitor.
